swissTLM3D
swissTLM3D is the large-scale topographic landscape model of Switzerland. It includes both natural and artificial landscape features, as well as name data in vector form. With a high degree of accuracy and the incorporation of a third dimension, swissTLM3D is the most extensive and accurate 3D vector dataset of Switzerland.

The large-scale topographic landscape model of Switzerland
Version 2.1
swissTLM3D is available for all of Switzerland and the Principality of Liechtenstein. The current release has the version name swissTLM3D 2.1. A PDF document containing a full overview of the swissTLM3D 2.1 data catalogue, including a list of modifications made in comparison to swissTLM3D 2.0, is available in German or French.
News from swissTLM3D
The 2023 edition of swissTLM3D is now also available in GeoPackage format and contains all validated street names from the official index of streets.
Applications
swissTLM3D can be used for a wide range of applications thanks to its simple and clearly defined landscape feature structure:
- as a reference data set for establishing information systems (e.g. dynamic segmentation based on the road network of swissTLM3D)
- as a basis for 3D visualisations and analyses (depending on the application, in conjunction with swissALTI3D)
- as a database for simulations, plans and statistics
- as a starting point for publications (maps, plans, Internet) and finished products (e.g. multimedia, navigation or geomarketing)
